The K-curve (8–12× In magnetic trip) is specified for inductive loads such as motor and transformer circuits where high inrush currents are expected, avoiding nuisance trips on start-up while still providing short-circuit protection.","metaTitle":"ABB S283-K8W MCB 3P K8A 480VAC, current lifecycle","metaDescription":"ABB S283-K8W miniature circuit breaker, 3-pole K-curve 8 A at 480 VAC.
